M48T37Y-70MH6E Overview
There is an embedded version of real time clocks in the package 44-BSOP (0.337, 8.56mm Width) requires SNAPHAT.This package has a package type of Tube.Electrical RTCs such as this have a 4.5V~5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of -40°C~85°C.If Alarm, Leap Year, Watchdog Timer is ensured when operating, then the operation will be successful.There are 44 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 5V which is provided to it.A total of 44 pins are attached to this RTCs.There are a family named M48T37 that consarets of the RTCs .In the RTC times, there is a memory of 250kB that is available for storing programs as well as data.In this case, the RTC module is mounted in the way of Surface Mount.As a power supply for the real time clock, a value of 5V is used.The Timekeeper® series represents this type of real time clock.In this case, 70GHz is the highest frequency possible.A 8 bit digital time clock has been designed.
